Preparation and Photo-Catalytic Performance of ZIF-67@F-Ta₂O₅ Hetero-Structure

Article Preview

Abstract:

ZIF-67@Ta₂O₅ graded hetero-structure material was designed and prepared using F-Ta₂O₅ as a raw material and Zeolite imidazole ester(ZIF-67) as framework structure material. The hetero-structure Ta₂O₅ and ZIF-67@Ta₂O₅ were annealing 6 hours at 900°C in nitrogen ambience. The photolysis properties of the Ta₂O₅ and ZIF-67@Ta₂O₅ materials as catalysts for photocatalytic decomposition of water to hydrogen were characterized. The results show that the heterogeneous composite structure formed by cobalt-tantalum oxide and tantalum pentoxide can significantly improve the hydrogen production performance of tantalum pentoxide samples, and the properties of samples obtained under nitrogen atmosphere are better. Among them, the N-50 sample (F-Ta₂O₅ is 50mg, Cobalt nitrate dosage is 6ml, annealing 6 hours at 900°C in nitrogen ambience) has the best hydrogen production performance, and the hydrogen production rate is 116μmol/g/h.
